BALL-BEARING SlCKLE-BAR CLIP.

SPECIFICATION forming part of Letters Patent No. 727,864, dated May 12, 1903.

Application filed February 8, 1902. Serial No. 93,116. (N0 model.)

To all whom, it may concern:

Be it known that I, IRA TRIMBLE, a citizen of the United States, residing at Sterling,in the county of Rice and State of Kansas, have invented certain new and useful Improve-l ments in Ball-Bearing Sickle-Bar Clips, of which the following is a specification.

My invention relates to bearing-clips for mowing-machine sickles of that type having aball-bearing relation with the sickle for the purpose of eliminating friction in a large measure, and thereby lengthening the period which the sickle-bar remains in service, as well as the life of the wearing-plates; and my object is to produce a device which performs its function efliciently and is ofsimple,strong, durable, and cheap construction.

To this end the invention consists in certain novel and peculiar features of construction and organization, as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1 is a perspective view of a part of a mowing-machine equipped with a bearingclip embodying myinvention. Fig. 2 is a central vertical section of the same.

Referring to the drawings in detail, where like reference characters designate corre-. sponding parts, 1 designates the finger-bar of a mowing-machine of any suitable or preferred type; 2, the guards thereof, and 3 the sickle or cutter bar mounted in the guards and adapted to reciprocate therein.

A clip embodying my invention comprises the body-plate 4, placed upon the finger-bar in the usual position and provided with a pair of slots 5, extending transversely of said fin ger-bar and receiving bolts 6, projecting upwardly from said finger-bar. These bolts are preferably the same which unite the guards to said finger-bar, as shown, and their upper ends are engaged by nuts 7, which serve to clamp the clip rigidly at the desired point of adjustment, it being understood that the clips are adapted for adj ustment' for two reasonsone in order that they may accommodate machines of difierent type, and therefore proportions, and the other that they may accommodate wear of the parts to which they sustain an operative relation. Plate 4 is formed with an enlargement 8 overhanging the sickle, which enlargement is provided in its under side with a groove 9, slightly exceeding in length the movement of the sickle, 5 5

and extending parallel thereto and mounted in said groove and held by the plate firmly down upon the sickle is a roller, preferably in the form of a ball, 10, so as to eliminate friction as far as possible, this ball also serv- 6o ing to hold the sickle down in its proper position upon the guard and ledger-plate thereof in order that it shall cut with the greatest effectiveness. The clip is also provided with a rib 11, parallel with enlargement 8 and 00- cupying the space between the front edge of the finger-bar and the rear edge of the sickle, said rib being curved downward, so that its front side and the lower face of the bodyplate t form a ball-race 12, containing a roller or ball 13, which roller or ball bears against the rear edge of the sickle, and thereby holds the latter reliably forward to its work with a minimum of friction.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

The combination with the finger-bar,guards,

and sickle-bar of a mowing-machine of a clip consisting of a body-plate provided with lon- 8o gitudinal slots transverse to the length of the finger-bar; the plate having at its front end an enlargement provided with a groove, a ball in said groove and borne downward upon the sickle-bar, said plate also having a transverse integral rib curving downward in front of the finger-bar so as to leave a ball-race between the body-plate and rib, a ball in said race and engaging the rear edge of the sickle-bar, bolts projecting from the fingerbar up through IRA TRIMRLE.
